Specific surface area of hydrating cement also plays a role, but it cannot account alone for the effect of different polymer structures and dosages on the yield stress of a given cement. indeed, in this initial hydration period, the specific surface area remains rather constant and is not dependent on heat rate as shown in fig. 12.
